Fishing in Santa Catarina

Santa Catarina sits at the southern end of Brazil, where the climate cools enough that peacock bass — the dominant sport fish of the tropics — doesn't take hold. That shift shapes everything about the fishing here.

The state runs from a heavily developed Atlantic coastline inland through the Serra Geral highlands and out to the broad river systems of the west, and each zone fishes differently. The coastal scene around Florianópolis carries real history.

Barra da Lagoa, a traditional fishing community on the island's east side, has been working the canal and nearshore waters for generations.

Artisanal fishers there have long targeted tainha — a mullet species central to the local culture — but longtime fishers describe catches today as a fraction of what they were before the 1980s.

Tourism pressure and changing fish populations have reshaped the community, and the tension between traditional fishing and the island's growth as a tourist destination is ongoing and unresolved.

Offshore, the São Francisco do Sul area and the waters around Florianópolis support charter operations running oceanic trips, and the coast sees both recreational and artisanal effort year-round.

Inland, the freshwater picture is dominated by farm ponds and pay-lakes — locally called pesque-pague — stocked with species like pacu, tambaqui, and the hybrid tambacu.

These are social fisheries close to towns, built around a day out rather than a wilderness experience.

For lure fishing, largemouth bass have filled the niche that peacock bass occupies further north, and Santa Catarina and neighboring Rio Grande do Sul are considered the strongest bass states in Brazil, mostly on private waters.

The river systems of the west — the Rio Uruguai and its tributaries including the Rio Chapecó and Rio Chapecozinho — hold native species like piapara, a fish known for punching well above its weight on light tackle.

The Rio Itajaí-Açu drains the central highlands, and smaller coastal rivers like the Rio Cubatão and Rio Benedito run through the Serra before reaching the coast. The artisanal fishing communities here are worth understanding before you go.

What's happening in Barra da Lagoa — fishers pivoting to tourism, younger generations stepping away from the nets — reflects pressures playing out across the whole coast.

The fish are still there, but the abundance that older fishers remember isn't coming back on its own.
